NPIV Proxy Gateway: Terms and Definitions
The following table describes the terms used in an NPG configuration on the S5000.

Term Description
FC port Fibre Channel port on an S5000 FC module that
operates in autosensing, 2–, 4–, or 8-Gigabit mode.
On an NPIV proxy gateway, an FC port can be used
as a downlink for a server connection and an uplink
for a fabric connection.
F port Port mode of an FC port connected to an end node
(N) port on an S5000 NPIV proxy gateway.
N port Port mode of an S5000 FC port that connects to an F
port on an FC switch in a SAN fabric. On an S5000
NPIV proxy gateway, an N port also functions as a
proxy for multiple server CNA-port connections.
ENode port Port mode of a server-facing S5000 Ethernet port
that provides access to FCF functionality on a fabric.
CNA port N-port functionality on an FCoE-enabled server port.
A converged network adapter (CNA) can use one or
more Ethernet ports. CNAs can encapsulate Fibre
Channel frames in Ethernet for FCoE transport and
de-encapsulate Fibre Channel frames from FCoE to
native Fibre Channel.
DCB map Template used to configure DCB parameters,
including priority-based flow control (PFC) and
enhanced transmission selection (ETS), on CEE ports.
Fibre Channel fabric Network of Fibre Channel devices and storage arrays
that inter-operate and communicate.
FCF Fibre Channel forwarder: FCoE-enabled switch that
can forward FC traffic to both downstream FCoE and
upstream FC devices. An NPIV proxy gateway
functions as an FCF to export upstream F port
configurations to downstream server CNA ports.
FC-MAP FCoE MAC-address prefix — The unique 24-bit MAC
address prefix in FCoE packets used to generate a
fabric-provided MAC address (FPMA). The FPMA is
required to send FCoE packets from a server to a
SAN fabric.
FCoE map Template used to configure FCoE and FC parameters
on Ethernet and FC ports in a converged fabric.
